@jmarcelino Does that pin do anything when the Pysense is powered via USB?
When I measured the voltage on PWR_EN pin on external IO, it is about 2.53 volts (HIGH). I pulled the PWR_EN pin low, but the module continues to work. (0 volt on PWR_EN pin).
Can I use it to disable the module externally?

Unplugged USB. > The PWR_EN pin is connected to GND. > Plugged back in the USB cable.
Still the FiPy module works?
